  • Patent number: 8851572
    Abstract: A vehicle seat (1), in particular a motor vehicle seat, has at least one fitting (10) including two fitting components (11, 12) that can rotate relative to each other. At least one structural component (15) has at least one opening (16) for partially receiving the fitting (11, 12) and at least one mounting area (18) enclosing the opening (16) for mounting the fitting (10), by at least one weld seam (19) between the mounting area (18) and one of the two fitting components (11, 12). The mounting area (18) is reinforced by additional material relative to the other areas of the structural component (15).

  • Patent number: 8277710
    Abstract: The invention relates to biaxially oriented polyester films which contain 0.1-5.0% by weight (based on the weight of the film) of a hydrolysis stabilizer based on epoxidized fatty acid esters and 0.2-10% by weight (based on the weight of the film) of epoxidized fatty acid glycerides, the epoxidized fatty acid esters having a mean molecular weight of at least 425 g/mol. Such films find use in outdoor applications, as a ribbon cable, as a backside laminate of solar modules and in electrical insulation applications.

  • Publication number: 20070238816
    Abstract: The invention relates to a polyester film comprising a hydrolysis stabilizer, wherein the hydrolysis stabilizer is an epoxidized alkyl ester of fatty acid or is a mixture of epoxidized alkyl esters of fatty acid or is an epoxidized fatty acid glyceride or is a mixture of epoxidized fatty acid glycerides. The form in which the hydrolysis stabilizer is added to the polyester is that of dry liquid, absorbed by a carrier material.

  • Patent number: 7241507
    Abstract: The invention relates to a hydrolysis-stable polyester whose thickness is preferably in the range from 0.4 to 500 ?m. The film comprises polyester and at least one hydrolysis stabilizer and is distinguished by its low hydrolysis rate. The invention furthermore relates to a process for the production of the film and its use.

  • Patent number: 6900350
    Abstract: The invention relates to a method for the production of ?-aminoalkylsulphonic acids of general formula (I), where R1 and R2=optionally substituted alkyl groups with 1 20 C atoms and n=a whole number from 2 6, whereby an amine of formula (II), where R1 and R2 have the above meanings is reacted with an alkyl dihalide of formula (III), where n has the above meaning and X1 and X2=chlorine or bromine, with addition of alkali hydroxide at a pH of 8 10. The pH is then adjusted to a value of 0 1, by addition of a hydrohalic acid and excess alkyl dihalide is separated off, before the reaction solution is adjusted to a pH of 6 7.5 with alkali liquor, alkali sulphite is added and the product (I) formed at elevated temperate.

  • Patent number: 6623073
    Abstract: A headrest (1) for a vehicle seat, in particular for a motor vehicle seat, has a first assembly for contact with the occupant's head and a height-adjustable second assembly (25, 41). The first assembly (101) moves forward relative to the second assembly (25, 41) in the event of a crash. A third assembly (15) on the headrest (1) is provided beneath the second assembly (25, 41). The first assembly (101) moves upward relative to the third assembly (15) in the event of a crash.
